This code was never invoked since we had no native contract enabled
starting from some hardfork, Notary is the first one. And luckily, we
have plenty of tests that fail due to this bug.

It doesn't work for contracts enabled starting from non-nil hardfork:

It happens because ActiveIn hardfork wasn't taken into account during
`latestHF` computation. This commit also removes the reusage of
`activeIn` variable in deploy procedure, it's misleading and not
necessary startign from #3444.

Do not use the updated contract state from native Management to perform
permissions checks. We need to use the currently executing state
instead got from the currently executing VM context until context is
unloaded.

Account is blocked when it's in the Policy's storage, not when it's
missing from the Policy storage. Introduced in
bbbc6805a8.
This bug leads to the fact that during native Neo cache initialization
at the last block in the dBFT epoch, all candidates accounts are
"blocked", and thus, stand-by committee and validators are used in the
subsequent new epoch. Close#3424.
This bug may lead to the consequences described in #3273, but it needs
to be confirmed.

It's possible for transaction to include block hash into Conflicts
attribure. If so, then we must not remove block executable record while
cleaning transation's conflict records.

Conflicts-related code contains more and more these magic numbers, and
there's no good in it even if all the usages are commented. This
approach produces bugs like #3426.
No functional changes, just a refactoring.

Conflict record stub has value of 5 bytes length: 1 byte for
storage.ExecTransaction prefix and 4 bytes for the block index LE. This
scheme was implemented in #3138, and this commit should be a part of
this PR.
Also, transaction.DummyVersion is removed since it's unused anymore.
Close#3426. The reason of `failed to locate application log: EOF` error
during genesis AER request is in the following: genesis executable was
overwritten by conflict record stub produced by transaction
0x289c235dcdab8be7426d05f0fbb5e86c619f81481ea136493fa95deee5dbb7cc (ref.
#3427). As a consequence, an attempt to decode transaction AER was
initited, but conflict record scheme was changed in #3138.

Transaction
0x289c235dcdab8be7426d05f0fbb5e86c619f81481ea136493fa95deee5dbb7cc is
already on mainnet at block 5272006 and we can't do anything with it.
This transaction has genesis block hash in Conflicts attribute. It leads
to the following consequences:
1. Genesis block executable record is overwritten by conflict record
stub. Genesis block can't be retrieved anymore. This bug is described
in #3427.
2. Somehow this transaction has passed verification on NeoGo CN without
any warnings:

And thus, we must treat this transaction as valid for this behaviour
to be reproducable.
This commit contains two fixes:
1. Do not overwrite block executable records by conflict record stubs.
If some transaction conflicts with block, then just skip the conflict
record stub for this attribute since it's impossible to create
transaction with the same hash.
2. Do not fail verification for those transactions that have Conflicts
attribute with block hash inside. This one is controversial, but we
have to adjust this code to treat already accepted transaction as
valid.
